Please be advised that Batman....
.... has more important things to do than make speeches.
However, if you'll note the panel in the center of this page:
Batman apparently gives a lecture daily. By the oiled pectorals of Fabio, how lame is that?
This was a classic moment where Batman gets his feelings hurt by lack of public support. Because if the public won't support you, what's the point of being a masked vigilante operating outside the law?
Even at the end of the story, Bats is fishing for compliments:
In all the psychoanalytical articles I've read about Batman's issues, I've never seen anyone touch on this crippling self-esteem situation. It's kind of sad, really. Someone needs a hug!
See you tomorrow!
